To all 'whom 'it 'may concern:

Be itv known that I, IVILLIAM C. Fammi, citizen ofthe United States, andresident of Arlington, in the county-of Bennington and State of Vermont,have invented certain new and useful Improvements in Type-WritingMachines', of which the following is a speciiication.

My invention relates to typewriting machines andpmore particularly totabulating .mechanism therefor; and the object of my invention is toprovide simple and eicient mechanisinof the character specified.'

To the above and other ends which will hereinafter appear my invention'consists of the features of construction, arrangements of parts andcombinations of devices to he herel inafter'described and claimed.

Fig. l5) is a fragmentarydctail plan view of the guide block and illustrating guiding walls andarresting ahntments.

I have shown my invention -applied to a No. 6 Remington machine thoughobviously the invention may be applied to other characters oftypewriting machines.

The frame of the machine comprises a base l, corner posts 2 and a topplate 3, which latter has upwardly extending supports or lugs 4: and 5that support the guide or traverse rods 6 and 7 respectively. A

shift rail supports a traverse roller S) which is connected vto a platenframe 10 that carries a platen 11, the platen frame beingconnected bylinks l2 to the carriage'truclt 3, provided with traverse rollers liwhich coperate with the rod to support thev carriage and guide it in itsmovements from Side to side of the machine. Extending rearwardly fromthe truck is a guide arnil which connects with a sleeve 16 thatsurrounds the traverse rod 7. in order to assist in supporting the truckand guiding it inthe movement of the carriage from end to end of themachine.

A fulcrum bar or -weh 17 extends downwardly from the base plate of themachine and cooperates with the notched portions ot' .1.

liar.;4 and key levers are employed thoughl -onlv a single f vpc actionis shown.

llxtcnding under thc various key levers is a universal har 25 couucchulat its cudsto upwardly extending linlts t supported at their upper endson a transverse liar :27. This har is connected to a forwardly extendingarm 28 vonla rock shaft 29 mounted in bearings 3"of.lajlira cket plate3l which is secured to the top plate of the machine.- A spring 32 is connectedat one end 33 to the bracket plate and at its opposite end,isconnected by any 'suitable means to the rock shaft 29 and exerts ressure torestore the lparts connected thereto bearing piece or block 34 isapertured to receive .areducedportion 35 of the rock shaft andisadaptedtobe adjusted around the saine' and to be maintained in'itsadplate of the machine andhas one t curely-fastened in an opening ordepression' justed 'osition. Thus the arms 34" are formedI a bifurcationwhich extends transversely of and separates them and a screw 36 extendsthrough threaded openin s in the depending arms and is -effective to rawthe arms together and thus secure'thebearing piece by frictipnal contactin its adjusted position on the shaft. Rigidly connected to the bearingpiece is an upwardly extending arm 37 .which is split at .its upper endto form oppositely extending ingersBS and 39. lhe linger 39 is-seated ina lrecess' 40 of -a lever 4l which is pivoted at 42 von the top end of.a spring 43 connected thereto at 44, the opposite end of said springbeing connected at 45 to a pin which projects from a .fixed bearin 46.

The lever 4l has a disk 47 seated an setherein, said disk beingapertured at '48 to provide stops or abutments 49 a'nd 50. Projectinginto the space 48 betweeh the abutments 49 and 50 is a finger 51 thatprojects downwardly from the feed dog 52 securedto arock shaft 53 whichis adapted A,to turn in bearings' 54 forming a part of the hearing 46herelnbefore referred to. The

'feed dog 52 has an upwardly extending'bif urcated portion that formsstops 55 and 56 between which is received a headed pin '57 that projectslaterally from and is carried by a loose dog 458 that is free to turn onthe rock shaft 53. A spring 59 is connected at one end 60 to the fixeddog 52and at its other end 6l to the loose dog 58, and

'the tension of this is exerted to normally maintain the loose dog inthe position illus` trated in'Fi 7 with the stop pin 57 been ing againstt Vated in the following manners. afl-'j .n

The esca ement wheel 63 is rigidly secured to a shawhich rotates in bearings 66 and 67 and this shaft carries a feed pinion68 that is securedv thereto and which is in constant mesh with the feedrack'69 secured to the carriage truck. It will thereforeil'e 75understood that in the movement''oi'-'th'ev carriage from end to endof-thenachii'ie,

the feed pinion 68, shaft and escapejmeit wheel 63 rotate, and that therelati'orgof theseA parts is never changed. That isl to say, theescapement wheel Iwill always be in the saine position when the carriagemoves to a xed lpoint and the positionof the v escapexnent wheel dependsuponvthe position of the carriage.

It will be understood that the carriage. 1s

propelled by a spring drum '71 which is con- .nected at one end"to aband 72, the opposite end of which is connected at 73 to an arm 74 thatis secured tothe carriage and the tension of the spring drum is exertedtofmove the carriage in the direction of its feed, thereby effecting thefeed moyement of the carriage when the escapement mechanism is actuated, in the manner hereinbefore described.

The bearing 46 is provided with upwardly extending ears 75 that areapertured to receive and constitute bearings for a longitudinallysliding rod 76 that is headed at one end 77 to limit the movementthereof. Secured to the slidingrod 7G by a screw 78, is a stop 79 thatcomprises a bearing portion which is.

apertured for the passage of the rod therethrough and is extendedlaterally 1n order to form a tabulating s top member. The screw 78 isreceivd in a threaded opening in the bearing portion of a stop 79 andhears at its inner end against the rod 76 so as to secure the stop fixedupon the sliding rod 7G and to afford an adjustment of the stop on therod if necessary. The screw 78 extends beyond the bearing portion of thestop 79, as illustrated in Fig. 3, and constitutes a pin that is seatedin an elongated slot 80 in an actuating arm 81. The arm 81 isadjustablysecured to a rock shaft 82 which extends from side to side of themachine and outside of one of the. corner posts 2. This shaft isreceived in yopenings or bea-rings in the base of the machine so that itis adapted to rock therein and a screw 83 is received in a threadedopeningr in the hub 84 on the actuating .arm and hears at its inner endupon the rock shaft 82, sons to secure the arm to the rock sha ft and toafford an adjustment thereof 0n the shaft when desired. The free end ofthe rock-shaft s2. which extends beyond or outside of the frame of themachine, is rigidly connected to a' lahnlatine key lever 85 .which isguided at its forward` portion by a guideplate 8G secured hy screws *lto one of the corner posts oi' lhe n'lachine.

.spring S7 is connected at one end to the stop 70 as indicated at 90 andthe. opposite ein of this spring passes loosely' through an eye -91secured to vone side of the actuating -lever'81. The tension of thespring is exerted- -lowerniost position shown in Fig. 2 of the drawingsbut may be turned up against the tension of the spring 87 and around thelongitudinal axis of the movable rod 76, for purposes which willhereinafter appear.

The tabulating key lever and the parts connected thereto are normallymaintained in and restored to their normal positions by a contractilespring 94 connected at ene end to a corner post of the frame at 95 andat its opposite end to the tabulating key lever.

The forward end of this key lever is formed as represented in Fig.' 12with laterally extending supporting portions 96, each of which isapertured cent-rally at 97 and parall'el portions 96 on the sides of theparts 96 are apertured at 98 to form bearings for pins or pivots' 99,each of which is fixed in the bearing openings and passes looselythrough l an opening 100 in a key stem 101 of the tabulator key. Thisopening is sufficiently"large to Ypermit a lateral swinging movementofthe key stem as well as a fore and aft movement thereof around thepivot 98 so that the construction is such that a gimbal or universaljoint is' formed which permits a movement of n'ntation of the key headand affords a. movement of the key stein in -anv direction; thus,-

for instance it wil he seen the' t each' key head 102 constitutes tou:portie-ns or keys a, b, c, d, so that a pressure ed upon the portion a-will ca use the lower end of the associated key stem 101 to be moveddiagonally or in the general direction of the portion c as well as tocanse a downward movement of the stem and the key lever to which it isconnected. lf the finger of the operator bears upon the portion b, thelower end of the key stem will )e moved diagonally inthe generaldirection of the portion d and the key stem and key lever will at thesame time be depressed. It will be understood that the initial pressureexerted n on the key head will tend to deflect the rey stem in themanner described and that this movement takes place at the.

initial portion of the stroke of t ie key lever, so that it isimpossible to depress the key lever without first positioning thekeystem in the manner specified. The lower end of each key stem is slightlyflattened on four sides, as indicated at 103, and each key stem isreceived in a guiding opening 104 of aV guide block 105 which is securedto the ont side of the base ofthe machine by screws 100. The contour ofeach of lhc l{ 1-hiding openings 104 is rectangular in cross4 section,as indicated in Fig. 19, so that when the lower end of a key stein ismoved laterally into a corner L3-l of its guiding opening, two of theflattened sides 103 on the key stem will cooperate with two side wallsof the openingand the lowerl end of the-key stem will be guided in, its

downward movement, In the lower portion" of each guiding opening 104 isan arresting block or abutment 107 which is adj ustably secured in placeby a set screw S that is re ceived in a threaded opening in the block107 10 and bears at its inner end against the block in order to secureit in place. The upper face of each block 107 is stepped as indicated at109, -110, 111 and 112, which steps are at four different elevations andextend to the four corners 113 of the guidingA opening 104. Each of theblocks 107 is apertured 4centrally at 114 in order to allow-a key stemto pass therein, and toallo'w each of the key stems to be depressed itsfullest extent or ast the 'associated steps or faces 109 to 112 w en thekey stems are centrally positioned in the uidng openings 4104: and thekey lever is.A depressed. Eao key stem -is surrounded by 'a weight 115Athrough-which the stem slides loosely and which is-beveled at itslowerend drtion 116 where it is seated in the mouth of a guide opening101Jso aste normally center i f *itself by the Weight thereofand tomaintain the key stem rope'rly centered in the opening n so thatit be inalinement with the central lopening 114 in the block 107.

From anexamination of Fig. 1, it will be 4seen that'the keystems 101extend to diler-4 ent depths in the openings 104, and the constructionis such that the keypstem at' the forwardv end of the key lever may bedepressed and brought into contact with its lowest ar rest' sto 109before theke s tem'of the other eyA 1s brought to the eight. of the iohigteae-.epeming-aop 112.V 1min there..

It willbeunderstoo thatthe purpose of therweights 115 is, `as heretoforeexplained, to automatically center the key 101 ,55 and normallymaintain' them centered-with the openings 114 in the blocks y107,sof'that one key stem will pass into its opeing 114 and not limit orinterfere with the depres; sion of the key lever 85 when it is actuatedVi0 by the other' key head 102.-

' Thestop 7 9 is provided with a torwardl extending pin 117 that has acam face 118 si its forward end which is adapted to cope atewithan-upwardlyextending lu 119 prot jecting from thelooefdog 58, `so t at aforward movement of the pin brings the cam 118 into Contact' with theprojection of the loose dog, moving the dog against the ten- Sion of thespring 59 which normally maintains the dog in the fixed relation withthe fixed dog as shown in Fig. 7, where it is in a position to engageand hold the escapement wheel against advance-movement. .As heretime outof engagement with the escapement wheel so that when the cam 118 isactuated by a depression of the key lever 85 it eii'eets a release ofthe loose dog so that the carriage is disconnected or freed from theescapement mechanism and travels under the tension of the spring drum inthe direction on its feed.

The escapementwheel 63 is provided with rearwardly extending clutchteeth-120 that engage like clutch teeth 121 on a stop carrying barrel ormember 122 which is loosely 'mounted on the shaft 65 and is adapted torotate independently thereof when the clutch members 120 and 121 aredisengaged, so as to afford a rotary adjustment of the stop carryingmember relatively to the escapement'wheel. T he stop carrying member 122is provided with a series of outwardly projecting, radiating andspirally arranged tabulating or denominational stops 123, which in thepresent instance, are eight in number and are spaced apart so that thedistance be,

tween the sto s corresponds to a letter space movement o -the carriage.The construction and relative` arrangements of the parts are such, thatwhen the stopV 79 is moved forward by a de ression' of the tabulatingkey, the stop w' lbemoved to a position where the free end ,or engagingportion 7 9a thereof will be brought into `the path of one "of thespirally arranged -radial denominational stops 123 and willprevent afurther tofore explained, the fixed dog 52 is at thisrotation of thestopcarrier, the escapement wheel, shaft 6 5 ,"thefpinion 68 and will cause'an arrestof theoafrriage.The stop carrymember 122 has'its' clutchmember or teeth -121 normally maintained in engagementwith theteeth 120on the escapement wheelby a coiled expansion spring 124`that iscontained within the central hollow portion of the stop carrier, asillustrated in Fig. 11, andbea'rs at one end against the stop carrierand at its opposite end against a sleeve creol-lar 125 that is securedto the shaft 65 bly ascrew 126 which extends through the trealdd'opening in the sleeve and bears at its inper end against theshaft. ...co'ntrolling piece or member 127 is loosely seated on theshaft 65 and the hub of .this -controlling piece is provided with apinion -1-28,`all portions of theV controlling piece -bing rigidlyconnected or formed ifrom one piece. -The face or disk-like portion ofthe controlling piece has a stop arresting portion 129 anda cut-awayportion scarsa 130. The stop arresting portion 129 is graduated. asindicated in Fig. S, with indices which in the present instance areindicated by the numerals 1 2 3 all and 5 i that begin at the upperintersecting` point. lgietweeiiethe cut-away portion'and the stoparresting portion in Fig. 8; the numeral-1 extending from right to leftwhen viewed from the rear of the machine. To thev rear of thecontrolling piece, the shaft fi' formed with an eccentric portion 131 onwhich is loosely seated an actuator' 1.32 for the controlling piece,said actuator being l provided with oppositely disposed pawls or tet-th133 which are adapted to alternately engage the teeth of the pinion 12S;the disposition of these pawls with relation to the teeth of the pinionbeing such that when one of them is in engagement with the pinion, theother is disengaged therefrom. he actinitor 132 carries an extendedportion 134 that lslotted at. 135 where it engages a fixed pin 136`which prevents the actuator from turning butl enables it to receive atransverse oscillating mtvement'by reason of the connection thereof withthe eccentric 131. An expansion spring 13T is seated in an opening in abracket 54, shown in Fig. 3, and bears at its forward end against theactuator 132 so as to normally maintain the teeth 133 thereof inengagement with the teeth of the pinion 128. When, however, a pressureis exerted rearwardly by the fingers df the operator upon the actuator132, the teeth 133 are disen,f aged from the pinion and the controllingpiece with its pinion is free to be rotated independently of the shaft65, the actuator 132 and the stop carrier 122, and may be adjusted so asto.

bring the different indices or numerals 1 to 5 into position toyregister .with the end T91 of the arresting stop 79. When thecontrolling piece 127 has been adjusted to the desired Vposition in themanner described, pressure on the actuator 132 may be released and theteeth 133 thereon, Vor one of the teeth, will be brought into engagementWit-l1 the pinion 128.

1n the present construction the feed pinion 68 is provided with twelveteeth and the tscapement wheel 63 is likewise provided with twelve teethand a complete rotation of the escapement wheel andmshaft affords amovement of the carriage twelve letter space distances. It should beunder- ,stood` however, that these parts may he changed by enlarging ordecreasing the numbeuof teeth on the escapement wheel and pinion, so asto provide a greater 0r a smaller number of letter4 space movements ofthe carriage at each rotation of the shaft U71 without departing fromt-he invention. Basing, however, the operation on the conv struction asshown, it. should be understood that each complete rotation of theescapement Wheel, the shaft 65 and pinion 68,-affords twelve letterspace movements of the carriage and this effects a lateral`reciprocation of the actuator 132 from right to left and back again, orvice versa, and that this movement of the actuator 132 is in the natureof an escapement device and produces a movement. of the controllingpiece 127 from one numeral or index thereon to another. That is tosay,if the numeral 2 on the controller is in register with the end ofthe dogor tabulating stop 79, then when twelve letter space movements of thecarriage has been effected the controlling piece will have been moved inthe direction of the arrow in Fig. 8 to bring the numeral 1 thereon intosubstantial register with, and to bring the cut-away portion oppositethe free end of the stop 79, so that it is free to be moved forward andbeyond the controlling piece.

Having described the various features of the construction, I will nowdescribe in dctail the operation thereof. 1t should first be understoodthat the tabulating mechanism is so constructed and arranged that adepression of any tabulating key is effective to release the carriageand that the carriage may be arrested at the particular denominationalposition desired as determined by the ortion a, b, c or d of each keyhead 102 that depressed. If desired the mechanism may be set to arrestthe carriage at a particular columnar position without the necessity offirst arresting the carriage at the preceding columnar positions. Thatis to say, if' desired the mechanism may be set to arrest the carriageat the proper denominational position Within a column, suchdenominational position depending upon the key depressionv` and thecolumnar position being determined by the setting of the parts, and itwill b'e unnecessary to. first arrest the carriage at preceding columnsor columnar positions in order to secure the arrest of the carriage inits proper denominational position Within the proper columnar field.Thus, with the twelve letter space distances of the carriage el'ected bya single rotation of the escapement wheel, as shown and described, thecolumns are regulated at twelve letter space distance-s apart and thesecolumns may be located Where desired. If, for instance, the carriage ina complete run is adapted to travel seventy letter space distances,which are indicated by the usual. scale and pointer shown at 138 and 139respectively in Fig. 1, then five columns are provided which are twelveletter space distances from the bethe stop carrier and the stops thereonto any ter'ed weight 115 .will pass into ther desired position withreference to the escapenient wheel and consequently with reference tothe travel of the carriage. In this Ymanner the beginning ot the livecolumns may be varied.

Should the operator desire to employ all tive columns, it is merelynecessary to adjust the stops 123 above described to secure the properlocations ot the columns and the controlling piece 127 1s then adjustedas represented in Fig. 8 so that the'terminal of the cut-av1ay portion130, adjacent to the index numeral 1 3, is at the stop 79 and allows thefree 'end of the stop to clear the arresting portion 129 on thecontrolling piece.. A'. de!

pression oli the tabulating key lever will then effect a forwardmovement ot the stop 7 9 and the first portion ot' this movement isedfective to release the loose dog from engagement with the escapementwheel and the continuedmovement ot the stop ,79 brings the free endthereof into the path of one of the stops 123 on the stop carrier, thusarresting the carriage at the desired denominational position in thelirst column from the point where the carriage'is arrested, whether itbe the first, second, third, fourth or fifth column, and thedenominational position of arrest of the carriage will depend on whichkey is actuated in depressing` the keylever. Thus for instance, if thedecimal key be depressed, the eiect of such depression is to move thefree end of the rear key stem diagonally until y lumnar field of twelveletter spaces.

it is seated in the corner 113 of the guide block opposite the loweststop 109 with which the key stem is adapted to cooperate. This aliordsthe longest extent of depression of the key lever and moves thearresting stop through the longest distance towards the front ot themachine or into the path of the foremost of thefspirally arranged stops123 or the one which is nearest to the front of the machine, and thecarriage will move untilY the stops contact, when the carriage will bearrested at a point that enables an imprint to be made in the decimalposition in the column of ligures within the proper co- It, how- A"ever,the millions lt'ey 's depressed, the stem of the associated key Stemwill be moved intoV cooperation witlnand will be arrested by, thehighest associated stop or abutment 112. The key leverA will receive itsshortest eX- t'ent of depression and the tabulating stop 79 will bemoved forward throughout its shortest extent of throw and into the pathof the rearmost stop 123 or that which is nearestthe rear of themachine, and the carriage will be arrested eight letter space distancesin advance of the position which it would by a, depression of thedecimal key, and srou.

y It will be seen that during a depression of tile key carrying thedecimal mark, the other or forward key stem, being maintained ceuopening104 and will a ord no obstruction to the depression of thekey lever 85and when the' key carrying the millions mark is depressed the other keystem will remain centered with its opening 114. The stop 7 9 is beveledon its lower and outer side so that i'n the sliding movement thereof,back to the normal position, it rides up or cams over any ofthe stops123 that happen to be in its path and'the stop 7 9 during this movementturns on the axial center or" the rod 7 6 and is forced against thetension ot" the spring 87 which latter tends to move the free end ot thestop down to normal position as soon asl the stop 79 has cleared thedenominational stops 123.

rlhe controlling piece 12T may set so :that the carriage will bearrested at the proper denominational position in any of tive col,-

`umns which are twelve letter space distancesv apart from the beginningof one columnar field to the beginning of the next, and the parts mayalways be actuated to arrest the carriage at the particular .fielddesired after the controlling piece is s et. lf, for instance, theoperator finishes the writing at Y18 on the carriage scale and desirestotabnlateA in a columnar field beginning at 48, it is merely necessary todepress the necessar denominational key, say, that bearin fthe' mark1000. and the carriage will' e ar rested at the proper denominational,or thou sandths position in the columnar field and those fields whichprecede it will be excluded. This may be accomplished'by releasing thecontrolling piece 127 from the actuator 132 in the manner hereinbeforedescribed when the carriage is at the beginning of a .line and settingthe controlling piece so that the numeral a is substantially in registerwith the end of the stop 79 as shown in Fig. 9.' A depression of thetabulating key lever through a denominational'key, will at this timemove the stop 79 forward bringing it into contact with the rear face ofthe arrest- `bring thecam 118 into contactswith the loose dog, therebyfreeing the carriage-and enabling it to run in the direction of its'feed, while the stop 79, bearing as it does at this time, on thecontrolling piece, ede/cts a 120 retarding action to prevent thecarriage from running too rapidly. lt will be un derstood that thegreater the 'pressure a plied to the tabulator, the greater will teretarding tendency of the stop l79 on'jth controlling piece and theslower will bathe run of thel carriage. It the carriage is at thebeginning of the line when the'carriag released, it will require fourcomplete/rem;- lutions ot the escapement wheel to bringthe iid anat

carriage to a point Where Writing or tabularI Work may be produced inthe fourth .co-

lumnar field. This rotation of the escapement Wheel is effective toproduce four complete back and forth movements of the actuator 132 whichturns the controlling piece in the directionpf the arrow in 9 from theposition shown in said figure to that illustilated in Fig. S. In thislatter position the stop 79 free to pass the arresting portion 129 andto lie projected through the cutaway portion 130 of the controllingmember and to be moved 'into the path of the proper denominational stoplas determined by the denominational key depressed, and the carriageWill be arrested at the `oroper denominational position.

From an inspection of Figs. 15, l'ad 17, it Will be seen that eachtabnlating keystem 101 is rigidly connected to four keys or to a keyhead hai'ing four members a, b, c and d, by being riveted thereto at101a and that the metallic frame 121 of the key has four perforations,recesses or depressions t-herein, each having an inwardly projectingcircular flange or shoulder 142 that constitutes a seat foinv an indexdisk 1413 that bears the mark for the key and above the index disk is aprotecting, disk 141 of trans )arent material, such as glass orCelluloid. i bove the transparent disk, each openinfr has an under-cutcircular groove, seat or epression 145, and seated Within this groove isaf split ring 116 which is shown in detail in Fig. 16. This ringis madeof spring metal and has a tendency to spring outwardly and to lockitself inthe under-cut lgroove and to project over the transparent diskand thus lock and secure the disks 1&3 and 14st in position in the keyhead. It will thus be seen that a simple and efficient key headstructure is provided wherein the. parts can be readily and securelyunited or assembled and that the ring 142 may be readily removed whendesired'to replace either or both of the disks 143 and 144 which aresecured in .place by the ring.

From `the foregoing description it will be understood that thetabulating devices cooperate with. the carriage feed mechanism to elect. an arrest of the carriage at the proper ldenominational positions:That is to say, thedenominational stops are connected to the escapem'entmechanism and an arrest of the denominational stops effects an arrestot' the escapement wheel and thus arrests the carriage. It will likewisebe observed that the controlling` device 127 constitutes auto maticall)Tactuated blocking means for -preventing' an actuation of the tabula-tingdevices to interpose the stop 79in the path of one of the denominationalstops 123 until the carriage has reached a predetermined point in thetravel thereof andthat the point in the travel of the carriage when thestop adjustment of the controlling device 127.

It should be understood that from certain aspects of my :inventiondenominational tabulating mechanism'as such need not he employed. Thus,forinsta'nc, if a single stop' lis employed and the stop 75) be given asingle 'extent of throiv an ordinary tabulating device is provided'wherein the controlling device l127 may be set to prevent the arrest ofthe carriage z any columnar positrolling device isset. p
